Hi

I’m trying to programatically check the “Wrap text in shape box” - see attached screen shot
The chart I created is a ClusteredBar

@andysteady,

I have observed your comments. As we have requested you earlier please provide sample in form of presentation so that we may investigate further to help you out.

Sure
See attached, graph on the left has the wrap box checked, the one the right does not.
You can see the desired effect on the right where the labels do not wrap

            using (Presentation pres = new Presentation())
            {
                IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.ClusteredColumn, 50, 50, 600, 400, true);                    
                IChartSeries series = chart.ChartData.Series[0];
                foreach (IDataLabel label in series.Labels)
                {
                    IChartTextBlockFormat textBlockFormat = label.TextFormat.TextBlockFormat;
                    textBlockFormat.WrapText = NullableBool.False;
                    textBlockFormat.AutofitType = TextAutofitType.Normal;
                    textBlockFormat.MarginTop = 10;
                    textBlockFormat.MarginRight = 10;
                    textBlockFormat.MarginBottom = 10;
                    textBlockFormat.MarginLeft = 10;
                    label.DataLabelFormat.ShowValue = true;
                    label.DataLabelFormat.ShowCategoryName = true;
                }
                pres.Save("pres.pptx", SaveFormat.Pptx);
            }
